Despite the ubiquitous demolition and construction throughout Kunming, the city's air quality has improved dramatically in the last three years, according to government meteorological data.
Xinhua is reporting that Kunming's four urban districts recorded 90 days of 'excellent' air quality in the first 233 days of this year, surpassing the previous year-long record of 88 days set last year. The remaining 143 days of non-excellent air quality were rated 'good'.
Kunming recorded only 18 days of excellent air quality in all of 2006 and 52 in 2007.
Haikou, capital of the island province of Hainan, was the only major Chinese city with higher air quality than Kunming, Xinhua reported.
Although in some areas it is stricter than its US counterpart, China's air quality index draws criticism for leaving out ozone and 2.5 particulate matter – fine airborne particles linked to lung damage and thought by some scientists to be able to seep into the bloodstream.
Additionally, air quality is determined by averaging the results of stations throughout a city, allowing for the air in some areas of a city to be dirtier than the official rating given to that day's air for the city as a whole.
The Kunming municipal government's air quality goals for this year are for every day's air quality to meet 'excellent' or 'good' standards and for the city to record more than 100 days of excellent air quality.© Copyright 2005-2021 GoKunming.com all rights reserved.
